Enough detail is available to trust this assessment.
Assessment Reasoning
Worldwide rollout has been pushed from mid-August to late August and will finish early September, so timing has changed but the feature remains enabled by default. Admins should review Copilot settings and compliance considerations, as Power BI grounding introduces data sharing with Fabric and new AI behaviours. End users will gain a visible capability to query data via Copilot, affecting workflows and prompting staff awareness. Admins have minimal configuration control through the admin centre but must assess governance and licensing implications.

ROLLOUT TIMELINE

Upcoming:
Late August 2026

📢 Official Microsoft Message Center Announcement

(Updated) Power BI integration with Microsoft 365 Copilot
Message ID: MC1323266 (Updated)

Updated August 19, 2026: We have updated the timeline. Thank you for your patience. 

[What and Why:]

Beginning in mid-June 2026, Microsoft 365 Copilot will be able to answer user questions using Power BI reports and semantic models for customers enrolled in Frontier. Copilot will ground responses in Power BI data, including scenarios where users share a specific report and scenarios where Copilot finds the right report automatically. The experience is built to work within existing security and permission models.

[Rollout Schedule:]

Data answering capabilities grounded in Power BI content will roll out across Frontier and Worldwide environments on the following schedule:

  • Frontier Private: June 17, 2026 (applied to TAP, TAP Subset, and AIX00)
  • Frontier Public (Entra): June 22, 2026
  • Worldwide: Starting late August 2026 (previously mid-August), expected to complete by early September 2026 (previously late August)

[Impact on Your Organization:]

  • Who is affected: Organizations using Microsoft 365 Copilot and Power BI that are enrolled in Frontier
  • Platforms/Services: Microsoft 365 Copilot, Power BI, Microsoft Fabric
  • Licensing requirements:
    • Microsoft 365 Copilot (Premium) license is required to use this feature.
    • Use of Fabric content, including Power BI reports, will be subject to the usual Power BI licensing to view content in the service.
    • Users are not required to have access to Fabric Copilot. 
  • What will happen:
    • Users can ask Copilot questions grounded in Power BI reports and semantic models.
    • Responses respect existing Power BI and Microsoft 365 permissions.
    • The feature is enabled by default. Admins can disable the feature through the Microsoft 365 admin center.
    • To generate responses, Microsoft 365 Copilot will search and retrieve data stored in Fabric, which means user query data from Microsoft 365 Copilot will be shared with Fabric. Fabric operates separately from Microsoft 365 Copilot and is subject to different commitments. Data processed in Fabric is subject to Fabric’s Product Terms.
